I noticed that almost all types of cooking oil (vegetable oil, olive oil, peanut oil, etc) contain some saturated fat. Since saturated fat is known to be a contributor to heart disease, then could you simply remove the saturated fats from the oil to make it healthier?
Could it perhaps be that the hamburgers cooked in grease and butter and ice cream being loaded with sugar are the issues?
Grease contains a large amount of saturated fat. As for ice cream, added sugars are unhealthy too, but since a lot of other unhealthy foods don’t contain sugar we know it isn’t the only cause.
